MONTE VISTA ― The Colorado Department of Transportation on Monday, March 29, began repairing an aged culvert on US Highway 285 just north of Monte Vista. The exact location of the US 285 project is at MP 52.3 approximately one mile north of the US 160 and US 285 intersection. The old 18-inch corrugated metal pipe culvert will be replaced with an improved 24-inch reinforced concrete pipe. The work take place through Friday, April 2. Two lanes of traffic — northbound and southbound — will be maintained throughout the duration of the project, however motorists will encounter lane shifts. Travelers will also encounter a speed reduction of 40 mph through the work zone.
